Garmin 66W Dash Cam Wiring Help

Hey guys,

New here and looking for some help. I bought my GF a Garmin 66W Dash Camera for Christmas. I also got her the Parking Module Cable so it can be hard wired in and have constant power. I was wondering if anyone has any ideas on where I can run the wires to? I'm new to Toyotas and Dash Cameras so this is a lot different than adding aftermarket lights, lifts, engine stuff. Any advice would be greatly appreciated. Here is a link to the cable: https://buy.garmin.com/en-US/US/p/587564/

Thanks!

 

It’s really not much different than adding lights. The hardwire kits are generally 3 wires for 15, 30, and 85 (key on 12 volt, always hot 12 volt, and ground)

Pick up a voltage meter, 2 add a circuits, some small wire gauge female spade terminals and a small wire gauge ring terminal.

From the dash cam tuck the wiring in under the edge of the headline, remove the A pillar trim and route it UNDERNEATH the airbag so it doesn’t get in the if it deploys and go to the sure box under the dash. Use the voltmeter to find an always hot fuse and a key on fuse and use the add a circuit there. With the fuse removed verify which side is powered so you install and fuse it correctly. Put the spade ends on and plug them into the appropriate add a circuits. Ring terminal to an under dash bolt into metal for the ground, and fuse camera in the add a circuit according to its power specs - it’ll have some pretty tiny wires so it’ll be a small amp rated fuse. Don't over fuse it! You fuse to protect the wiring from fire not the component itself.


All in all it’s like 30 minutes of work when it’s a single channel setup with no rear cam.

 

Thank you for the advice. I read this the next day and due to the weather we knew we couldn't install it for a few weeks as it got real cold. I got the volt meter and add a circuit, but did not get the rest. The add a circuit comes with wires and connectors attached that'll attach right to the wiring for the camera. Do you, or anyone, happen to know where I can find a pinout of the fuses? It'll make it a lot easier so that I do not fry the camera when we hook it up. I;m ready to get this thing hooked up for her though because Atlanta drivers SUCK!

 

That’s what the volt meter is for, pick a fuse and check if it has voltage with the ignition on or off.

 

I was able to use the test light and found two that worked. Took me about an hour to check them and run the wire. Most of that time was spent trying to recover a 10mm socket I dropped behind some trim. I didn’t realize the fuse panel on the drive side had mini fuses. So luckily the add a fuse came with extra fuses to use and complete the circuit. She’s all wired up now though.
